BOTTLE-CAP- SPEGIFICATION forming part of Letters Patent'No. 769,021, dated August 30, 1904.

Application filed June 3, 190%. SerialNo. 210,947. (No model.)

the United States. residing in the city of St. 1

Louis, in the State of Missouri, have invented certain new and useful Improvements in Botv tle-Oaps, of which the following is afull, clear,

and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention. relates to a cap for closing the mouths of bottles, particularly bottles in which beverages are sold, the object of the invention being to produce a cap of simple, inexpensive, and eflicient construction that may be readily introduced into, the neck of a bottle and readily removed therefrom, also a cap that may be removed without liability of injury to the rim of the bottle-neck and which may be reapplied to the bottle'after it has been separated therefrom.

Figure I is a perspective view of my bottlecap. Fig. II is a longitudinal section taken through the neck of a bottle to which my cap is applied and the cap shown separated from the bottle-neck. Fig. III is'a longitudinal section taken through the neck of a bottle and my cap shown positioned therein.

1 designates a bottle-neck that is provided at its mouth with a socket 2, having a concave wall that terminates at its inner end in an annular rim-seat 3.

My bottle-cap consists, mainly, of a body 4:, This body'is centrally depressed to form a bottom portion 5, that has integral therewith the circular wall 6, from the top of which extends the annular rim 7. The rim 7 includes an inwardly-extending fold 8, that carries a cylindrical concavo-convex neck9, within which is a cavity 10, and beneath the bottom portion 5 of the. cap is an elastic disk 11, preferably of cork.

When the cap is introduced into the neck of a bottle, the neck. 9 of the cap, which is bottle-neck, is pressed into said socket against resistance and the elastic disk 11 is compressed. These actions are permitted, due not only to the elasticity of the disk 11, but to the pliability of-the cap-neck, owing to the body of the cap being of thin metal. As the cap is forced home into the socket 2 the disk 11 is carried to the rim-seat 3, at the bottom of the socket to thereby create an air. and liquid tight joint. cap-neck is forced home against its resistance and the elastic disk 11 is slightly compressed I the cap-neck will bear constantly with pressure against the wall of the socket 2 in the bottle-neck, and the disk by its elasticity will constantly press the cap-neck outwardly to increase the holding action thereof in the portion, a rim provided with a return-fold, a circular neck extending from said fold; and

disk seated within said neck, substantially as set forth.
